An overview of climate change vulnerability: a bibliometric analysis based on Web of Science database 总被引：4，自引：1，他引：3
Based on worldwide scholars’ 3,004 papers published in 658 academic journals in the Web of Science database on the topic of climate change vulnerability from 1991 to 2012, this paper quantitatively analyzes the global scientific performance and hot research areas in this field by adopting bibliometric method. The results show that (1) the vulnerability researches on climate change have experienced a rapid growth since 2006, and the publications are widely distributed in a large number of source journals, while the top two productive institutions are the University of East Anglia and Potsdam Institute for Climate Impact Research; (2) the cooperation at author level is on the rise, and there are closer relationships in institutional and national levels; (3) the most widely focused research topics in this field include health issues in the socioeconomic system, food security in the field of agricultural system and the issue of water resource management, etc.; (4) according to the papers from the top journals, we find that the research areas for climate change vulnerability in those publications are located in the ecological diversity, ecosystem service, water resource management and electric power supply, etc. 相似文献

Interest in organic waste(water) processing by anaerobic digestion to produce biogas as renewable energy source has increased significantly in recent years. The characteristics of the digested effluents vary depending on the feedstocks treated, and different handling alternatives are possible. This study reviews advances in science and technology in the specific field of nutrient (nitrogen and phosphorus) management from biogas digester effluents during the last two decades (from 1995 to 2014) using a bibliometric approach. Information concerning publications as representative of the outputs of scientific research, and concerning patents as representative of the outputs of technological development was retrieved from specialised databases and analysed systematically. The number of publications was twice the number of patents. Production followed a rising trend (in both cases, partial productivity in the last 5 years was >45%). The USA, China, and Japan were the three most prolific countries when considering the joint production of publications and patents. However, while the number of publications was higher than the number of patents for the USA, the opposite was true for China and Japan. The institutions which published more (and also the most cited items) were mainly European, whereas Asian countries were more active in filing for patents even though the patents from the USA were more frequently cited. Relative interest in particular nutrient management alternatives and their evolution were identified. Reducing the consumption of resources, implementing integral solutions, and circular economy approaches will be among key issues in future studies and development to promote sustainability. 相似文献

This article examines how jurisdictional fragmentation has been addressed in Ontario’s governance of the Great Lakes Basin from 1912 to 2012. The water resources literature has frequently lamented fragmentation in water governance and called for integration; however, it infrequently specifies how and what to integrate. By examining key moments in water quality and quantity governance, this study provides insight on how the presence or absence of particular institutional arrangements in the context of jurisdictional fragmentation produced different governance patterns and outcomes. Specifically, to determine governance patterns the study focused on four elements: an institution that facilitates coordination, agreement on roles and responsibilities, agreement on the issue management plan, and the scope of the issue. Combinations of these elements can produce governance patterns that are cooperative, conflictual or reactive and outcomes that are innovative, stagnant, or piecemeal. The study results suggest that when governing in the context of jurisdictional fragmentation efforts may best be directed at particular institutional arrangements. Further, it suggests that jurisdictional fragmentation be understood as a feature of the institutional complexity of water management that can be mobilized to develop unique solutions to multi-scalar water governance challenges. 相似文献

The EU biofuels market is stimulating expansion of oil palm plantations in Indonesia. Little research has yet examined the impacts on water resources arising from this large-scale land use conversion to cultivation of biofuel feedstock or positioned contextual water resource governance in Indonesian locales in a wider political ecology of European climate politics. Through the concept of ‘hybrid accountability’, we examine primary evidence from an extensive action research process in Central Kalimantan Province, Indonesian Borneo, to assess whether the EU’s Renewable Energy Directive and existing certification schemes offer a way to improve the accountability of market actors and promote sustainable water resource management. We conclude that these initiatives have had no bearing on safeguarding local livelihoods and the water resources they depend on, with governance mechanisms largely failing to address people’s grievances. Rather, the EU’s policies on biofuels have supported a de-politicisation of what needs to be seen as ‘distributional water politics’. Furthermore, certification schemes such as the Roundtable for Sustainable Palm Oil offer, at present, only cosmetic tools and are insufficient to address deep structural governance issues. We argue that further hybridisation of market-based certification and governmental regulation should be designed with the purpose of providing new transnational recourse mechanisms and remedies for affected communities. 相似文献

水资源管理制度超模博弈分析——以钱塘江与黑河为例 总被引：2，自引：2，他引：0
运用超模博弈理论,以流域水资源管理制度形成的角度来解释流域各区段水资源管理政策执行面临的外部环境约束与激励,并通过模型描述了水资源管理域与外部关联域之间的博弈关系。分析发现：超模结构在当前钱塘江与黑河流域的水资源博弈中发挥着重要影响。钱塘江流域水资源管理制度收益函数对水功能区治理变量和经济域治理变量有递增差异。黑河流域水资源管理制度收益函数对分水治理变量和社会域治理变量有递增差异。由于这种关联作用对各区段主体策略集的限制,流域间水资源管理制度逐渐异质化,各流域管理结构呈现出一定的区域特色。钱塘江流域水资源管理偏重于扁平化、职能化管理,黑河流域为科层结构下水资源的层级分配。并依据以上研究结论提出了制度建议。 相似文献

Water rights adjudications lie at the intersection of law, space, and the geography of resource governance, combining elements of field cartography, archival research, and judicial supervision and decree. However, few geographers have examined the water rights adjudications now active in most western US states. Using case material and ethnographic vignettes from a larger geographic project on water rights and governance in New Mexico, I examine water adjudication as a vital instrument in the state’s pursuit of spatial knowledge. Resources and water users are seen by the state through this process, while at the same time, water users may elude or confuse state legibility. In this process, altered forms of governance are produced. Here, I explore how the formalizing of water rights in New Mexico has articulated new legal-spatial relationships, which are often viewed differently by state and local agents. I then examine the products of adjudications and the tension between local and expert knowledge in natural resources governance over being seen and governed by the state and the struggle to retain local autonomy and governance in water management. 相似文献

Michel Valladon 《Geostandards and Geoanalytical Research》2007,31(4):395-409
A total of twenty-five bibliographic reviews were published between 1979 and 2004 in Geostandards Newsletter, subsequently renamed Geostandards and Geoanalytical Research, which list more than 5500 papers. These cited references contain information about geochemical reference materials, analytical methods or address general issues concerning the use of reference materials (protocols for sampling, certification, or new analytical techniques). In support of emerging fields of interest in geoanalysis, frequently associated with environmental research, and reflecting the increased breadth in the topics addressed by the Journal, new reference headings were added over time, while retaining the original style and format of the review. Reference management software was used to extract information from these publications related to methods, reference materials and analytes. Major developments during these 25 years, reflecting both advances in laboratory hardware as well as shifts in research interests, can readily be seen in both the types of reference materials being studied and in nature of the new analytical protocols that were developed. These two topics were the core foci of the twenty-five reviews, though much more information might also be extracted from this extensive resource. 相似文献

Significant changes in the regional energy process, water recycling and the biological process have taken place due to the climate change and human activities, and the regional agriculture has been affected by these changes. It is therefore a key issue for the regional agricultural water resource management to accurately monitor and evaluate the change of crop evapotranspiration under a changing environment. The development of the evapotranspiration theory was first reviewed, and then, the driven mechanisms and the research progress of crop evapotranspiration were illustrated. The suitability of the current monitoring method and evaluation model of the evapotranspiration in the crop evapotranspiration research under climate change were analyzed. After that, the current studies of the agricultural water resources management of “ET-based” were reviewed, and finally, the research tendency of the crop evapotranspiration on the theory, methods and application management in the future were prospected. 相似文献

Water resource is the focus and hinge between ecological environment and socio-economic development. Watershed is the basic unit of hydrology and water resource studies. It is the current hotspot in water science research to carry out the integrated research of the hydrology and water resource at the watershed scale. The Heihe River Basin is the second largest inland river basin in northwestern China, which becomes one of the hot watersheds for its unique hydrological and geographical characteristics. Based on the Web of Science Core Collection, the scientific advances achieved in the Heihe River Basin were estimated from the new sight by combining disciplinary development and problem focus, time evolution and spatial variations. The results indicated that the Heihe River Basin has made positive contribution to the world science in remote sensing, evapotranspiration, water cycle, water resources management and utilization, and climate change research in arid areas. The great achievements has promoted the Heihe River Basin up to the same levels as the international typical basins in the past 30 years, especially after the performances of the major research program entitled “Integrated Study of Eco-hydrological Processes in the Heihe River Basin” (referred to as “Heihe River Program”) supported by a grant from the National Natural Science Foundation of China and large field observation experiments. The number of published articles has ranked the top 20 in the global watershed science research. Some important scientific achievements have been obtained at the mechanisms of eco-hydrological processes in inland river basins, which can actively serve the decision making of the water resource management and sustainable development in the Heihe River Basin. The data mining and contrastive study based on bibliometrics can afford scientific reference for the watershed science research. 相似文献

Security evaluation has become a hot topic in the research field of water resource management. In this paper, we established
a novel water resource security indicator system based on the Pressure-Status-Response (PSR) framework using gray relation
analysis (GRA) and technique for order preference by similarity to ideal solution (TOPSIS). A case study of Beijing from 1996
to 2007 was conducted to verify the evaluation system. Results showed that the gray relative closeness degrees of water resource
security to the positive ideal solution were low, with the least one of 0.360 in 1999 and the largest one of 0.527 in 2007,
implying that Beijing was facing severer challenges with water resources during the concerned time. Also, the analysis of
water resource security indicated that the pressure of water resource was constantly increasing. Finally, factor analysis
was employed to calculate the gray relation degrees of evaluating indices with the ideal solutions so as to reveal the relativity
of water resource security of Beijing, which may contribute to a better understanding of the urban water resource management
and regulation. 相似文献
